# Installation

Via CommandBox:

```bash
install cbelasticsearch
```

## Requirements

* Coldbox >= v6
* Elasticsearch >= v6
* Lucee >= v5 or Adobe Coldfusion >= v2018

{% hint style="danger" %}
*Note: Most of the REST-based methods will work on Elasticsearch versions older than v5.0. A notable exception is the multi-delete methods, which use the* [*delete by query*](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/docs-delete-by-query.html) *functionality of ES5. As such, Cachebox and Logbox functionality would be limited.*
